Patel Hyperscaler Google and Constellation Energy, the largest nuclear operator in the U.S., have signed a 20-year power purchase agreement (PPA) designed to support $4.3 billion of upgrades at 11 nuclear units across the PJM Interconnection, which is slated to add 890 MW of generating capacity from Constellation’s existing reactors by the end of 2032.

The companies announced the agreement Oct.

6 as part of a broader strategic energy collaboration that also includes a separate 15-year supply agreement covering 2,700 MW from Constellation’s existing PJM fleet.

Constellation said the 890 MW of incremental capacity will come from equipment and technology upgrades at 11 nuclear units across six sites in Illinois, Pennsylvania, and New Jersey.

The first uprate is expected online by 2028.

In a blog post , Google said all 890 MW would be online before the end of 2032.

The scale makes the agreement one of the largest corporate-backed nuclear uprate programs announced to date and adds another major tranche of existing-reactor expansion to PJM.

It arrives one week after Constellation signed a separate nuclear agreement with Amazon, announcing a 20-year agreement that covers 690 MW from the 1,790-MW Calvert Cliffs nuclear plant in Maryland, including an approximately 190-MW uprate expected online between 2030 and 2032.

Constellation said its agreement with Amazon will support more than $3 billion of investment at Calvert Cliffs and help support relicensing the two-unit plant for another 20 years.
